Agreement: negative/fear context lowers valence ratings of an unchanged neutral face in the four studies whose valence direction is stated in text (Mobbs reports a significant effect, direction in a figure). Conflict: the happy-context effect, the arousal direction (fear raises arousal in Calbi and Cao Exp 2, but unpleasant context lowered arousal in Mullennix), and the forced-label effect (present in Calbi, partial in Mullennix, absent in Szaszko & Loebus). Effect sizes range from partial eta squared about .64-.67 (Cao) to Cohen d 0.05-0.08 (Szaszko & Loebus) and are not comparable. Several published numbers do not reconcile internally (Cao Fig 3 caption, Mullennix arousal eta squared, Szaszko Table 2 'd' column), so exact figures should be taken from tables, flagged, and not mixed across papers.

Curator qualifications: Curator amendment CA-AM-0022 (2026-10-22): Curator df note withdrawn: with three within-subject conditions a multivariate repeated-measures test (Hotelling's T2 / Wilks) has F(k-1, n-k+1) = F(2, n-2), so F(2,29) for n = 31 and F(2,57) for n = 59 are consistent with that test (lead response C3-B034-FB56 FB6-0002). The caption-vs-text finding stands, and the lead adds that the caption's 0.005 equals the intensity test's eta2p (0.26/57.26), i.e. apparently carried over.

Conflict: the happy-context effect, the arousal direction (fear raises arousal in Calbi and Cao Exp 2, but unpleasant context lowered arousal in Mullennix), and the forced-label effect (present in Calbi, partial in Mullennix, absent in Szaszko & Loebus). Effect sizes range from partial eta squared about .64-.67 (Cao) to Cohen d 0.05-0.08 (Szaszko & Loebus) and are not comparable. Several published numbers do not reconcile internally (Cao Fig 3 caption, Mullennix arousal eta squared, Szaszko Table 2 'd' column), so exact figures should be taken from tables, flagged, and not mixed across papers. · locator: cited at https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0308295&type=printable; Cao et al. 2024 PLOS ONE printable PDF (pdftotext) · source: https://journals.plos.org/plosone/article/file?id=10.1371%2Fjournal.pone.0308295&type=printable
